We find evidence for distinct historical periods of positive and negative moods, underlain by a general decrease in the use of emotion-related words through time. Finally, we show that, in books, American English has become decidedly more “emotional” than British English in the last half-century, as a part of a more general increase of the stylistic divergence between the two variants of English language.</p> </div>", "links"=>[], "tags"=>["emotions", "20th", "books"], "article_id"=>656345, "categories"=>["Information And Computing Sciences"], "users"=>["Alberto Acerbi", "Vasileios Lampos", "Philip Garnett", "R.
